BOTTLE-FILLING. MACHINE.

SPECIFICATION forming part of Letters Patent No. 280,234, dated June 26, 1883.

Application filed April 1, 1882. (No' model.)

To all, whom it may concern/.

. Be it known that I, WVILLIAM PEARSON, of Carson. City, in the county of Ormsby and State of Nevada, have invented certain new and useful Improvements in Bottle -Filling Machines, of which the following is a full, clear, and exact description.

My improvements relate to machines for bottling soda and other gaseous liquids; and it consists incertain novel features,and in the arrangement and combination of the mechanism,whereby one or more bottles can be filled atonce with great facility, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of my improved machine, partially in section. Fig. 2 is an end view, partly in section; and Fig. 3 is a detail section of one valve-chamber. Fig. 4 is a detail view of the bottle-valve, and Fig. 5 is a vertical sectional view of my machine.

A is the main frame or bed of the machine.

a a are side frames rising above the bed,and

connected near their upper ends by a cross.

bar, a.

b is a cross-head provided at its ends with gibs b, that engage the frames a, 011 which the cross-head moves up and down.

0 c are levers hung on a cross-rod, c, and connected by a cross-rod, d, from which rods (1 d extend to the cross-head b.

e e are rods connecting levers 0 with a foot lever, e, and rock-shaftf.

f is a weighted arm on the rock-shaftf.

B B are valve-chambers carried by cross-- head I). 9 is a force-pump-one or two-sustained on one of the standards a, and connected to the several valve-chambers B by a pipe, g and flexible tubes 9. s

1L is an air-chan1ber connected on pipe 9. h h are flexible tubes connecting to the valvechambers B for supplying water from the fountain. h is the suction-pipe of the pump. 1' z" are cocks in the tubes and h, respectively, for regulating the supply of material to the valve-chambers. 7c is a pivoted beam connected to the piston or pistons of pump or pumps, as the case may be, and also connected to ahand-lever,k, for operation of the pump or pumps.

0 is the box for containing the bottles, fitted to slide on rails Z on bed A, and constructed of a size to receive four bottles transversely of the box, or other number corresponding to the number of valve-chambers.

m is a hook hung on the inner end of handlever It" for engagement with pins m on the side of box 0.

a is a spring fitted to act on foot-lever e to assist the upward movement of the cross-head.

The construction of the valvechambers is shown most clearly in Fig. 3. The water-supply tube 71 and supply-tube g for sirup enter the upper part of the hollow chamber, and the chamber is formed with a seat for a valve, 0, which, when closed, cuts off the material from the lower part of the chamber. The chamber is formed with shoulders 0, that rest on the cross-head b, and below the valve 0 the chamber is recessed or formed with a depending flange, on which is a concave nut, 11. Aring, p, of rubber, is interposed between the nut p and head I), so that .while the nut clamps the chamber to the head the rubber ring allows a slight vertical movement suflicient to equalie the height of the bottles. The nut 1) serves also to retain a beveled ring, q, of elastic material, which is for the purpose of guiding the neck of the bottle to place and holding it water-tight while being filled.

1' is an escape-valve fitted on the side of the valve-chamber, and communicating by a passage, r, to the interior spacebelow valve 0, be ing closed when the valve 0 is on its seat.

The bottles shown at s are provided, as shown most clearly in Fig. 3, with valves t, that are disks of concave-convex form, shaped to fit the interior of the bottle-necks. The valves t are on the ends of stems 1 that extend up to the mouth of the bottles for contact with valves 0, and the stems t are provided with loops or ends taking on the bevel of the bottlen1outh to limit the inward movementof the valve.

On the lower end of valve 0 are spring-fingers u for clutching the valve-stems 15, so as to raise the valves t at the upward movement of the valve chamber. used when the bottles are being filled with These spring-fingers are i 2' smesi slightly-gased liquids not having force enough to throw the bottle-valves upward. WVith highly-gased liquids, the sudden force on the concave under side of the bottle-valves being sufficient to close the valves, the spring-fin gers may be dispensed with.

The operation of the machine is as follows: The first row of bottles in box 0 being in position below the valve-chambers B, and handlever is raised, and thereby lifting the piston of pump 9 and charging the pump with sirup from suction-pipe h, the foot-lever c is then to be depressed, which brings the cross-head b and valve-chambers B down, and the lower portions of the valve-chamberspressing upon the bottle-heads, the valves 0 of the chambers are pressed open. The handlever 7c is then moved downward. The pump -piston is thereby brought down and the sirup forced through the valve-chamber into the bottles. At the same time the hook on is carried to the next pin m on box 0. The foot-lever c is then allowed to rise, thereby raising the valvechambcrs and allowing their valves 0 to close the bottle being charged, and the hand-lever is then raised, with the effect to move the box Z) forward and bring the first row of bottles beneath valve-chambers B or second row ofchambers, while another row ofbottles is brought beneat-h chambers B. The next depression of the foot-lever and descent of the cross-head sirups the second row of bottles, and the first row is in the same manner filled with the wa ter supplied to chambers B by pipe h.

In filling the bottles with liquid not liable to foam, both the water and sirup may be put in through one valve-chamber. and one set of valves. In that case the sirup-pipes y will connect to chambers B, as shown in Fig. 3, by any suitable connection, and the hook on will be reversed in position, so as to move box 0 in the reverse direction of the arrow. The pump will force the sirup into the valve-chamber and drive the waterback, and, beingmore dense than water, will lie at the bottom of the valve-chambers, so as to enter the bottles first when the valves are opened, the water followare shaped to the form of the bottle-mouth, as shown most clearly in Fig. 4, so that they prevent the valves falling into the bottles. This arrangement is to be distinguished from loops heretofore used, extending above the bottlemonths, 'and which could not be used in this 9, water and sirup tubes g 71., and the sliding box 0 for containing the bottles, substantially as described, combined for operation by levers, as specified. d

2. In bottle-filling machines, the sliding box 0, having pins n, and the hand-lever k, carrying the pawl m, in combination with the reciprocating valve-chambers B B, substantially as shown and described.

3. The combination, with the valve-chamber B, having valve 0, and recessed lower portions for receiving the upper end of a bot-- tie, and an elastic ring, of means, substan tially as described, for reciprocating said valve-chamber, a beveled elastic: ring, q, and a bed supporting the bottle, substantially as described, and for the purpose set forth.

4.. The combination of the head I), carrying the valve-chambers, the levers c, rods (1 e, and foot-lever c, substantially as described, for op eration as specified.

5. The combination of the pump (1, beam 7.,

hand-lever 7c, and connections, substantially,

as shown, with the valve-chambers B, for operation as specified.

6. The combination, with the filling-head, of the valve 0, provided with fingers u, which are adapted to grasp the bottle-stopper and assist its closing, substantially as set forth.

7. The spring-fingers a, combined with the valves 0 and chambers B,'substantially as and for the purposes set forth.
